you both love each other deeply.. But never talked about it because you both were scared of rejection and awkwardness..

now.. You were both fighting Mahito and you noticed how Mahito was going to attack Megumi , Megumi didnt realize, so you ran to him and took the shot instead of Megumi.

as soon as you got shot Megumi's eyes were widened meanwhile Mahito smiled and left

You fell right in front of Megumi trying lot to make any noise, the shot was very near your neck.
